How do I find the factor combinations of the number 143,039?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 143,039, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 143,039
-1 -143,039

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 143,039.

Example:
1 x 143,039 = 143,039
and
-1 x -143,039 = 143,039
Notice both answers equal 143,039

With that explanation out of the way, let's continue. Next, we take the number 143,039 and divide it by 2:

143,039 ÷ 2 = 71,519.5

If the quotient is a whole number, then 2 and 71,519.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 143,039
-1 -143,039

Now, we try dividing 143,039 by 3:

143,039 ÷ 3 = 47,679.6667

If the quotient is a whole number, then 3 and 47,679.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 143,039
-1 -143,039

Let's try dividing by 4:

143,039 ÷ 4 = 35,759.75

If the quotient is a whole number, then 4 and 35,759.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 143,039
-1 143,039
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

11311,003143,039
-1-13-11,003-143,039
